The bike thing is only one of the many things I have tried, there are numerous examples (that was just one of the more expensive ones).

As far as getting involved with a church, groups, etc... I'm always the wall flower. I'm too scared to say or do something in fear of being considered stupid.

I always wanted to be the person who was carefree and not afraid to be the center of attention. I've tried doing this in the past and ended up just crawling into my hole a little deeper than before.....
